Dietary Life, Vitamin D Status and Blood Clinical Indices of University Laboratory Workers: Jung Hyun Hwang, Hong Mie Lee, Jung Hee Kim; Korean J Community Nutr 2019;24(3):245-256. Published online June 30, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.3.245

Abstract PDF PubReader: OBJECTIVES
Although the number of laboratory workers is constantly increasing every year, few studies have been conducted on the health and nutritional status of these research workers. This study determined the health status of laboratory workers by analyzing their anthropometric indices, dietary life, vitamin D status and blood clinical indices.
METHODS
The subjects consisted of 100 female laboratory workers. This study investigated their diet, anthropometric indices, vitamin D status and blood clinical indices. The subjects were divided into two groups according to their duration of working in a laboratory (<1 year,â‰¥1 year).
RESULTS
The average age and body mass index (BMI) of subjects were 23.18 years and 21.51 kg/m2, respectively Those subjects with over 1 year employment (â‰¥1 year) had a significantly higher waist-hip ratio than that of the subjects with the less than 1 year employment (<1 year). The mean serum vitamin D level of all the subjects was 10.04 ng/mL, which is close to a level of vitamin D deficiency. There was a significantly higher average intake of calories in the over 1 year employment group as compared to that of the less than 1 year employment group. The frequency of eating sweet snacks was significantly higher for the over 1 year employment group. The correlation analysis showed a significant positive correlation between the serum 25-(OH)-vitamin D level and the time of exposure to sunlight, while dietary intake of vitamin D did not show correlation with the serum 25-(OH)-vitamin D level. However, the serum 25-(OH)-vitamin D level was also negatively correlated with both the percentage of body fat and visceral fat.
CONCLUSIONS
Laboratory workers are a very high risk group in terms of their nutritional status of vitamin D. Therefore, they need greater time of exposure to sunlight as well as increasing their dietary consumption of vitamin D. In addition, it is important for laboratory worker to practice regular and balanced dietary habits in order to maintain a healthy life.

Analysis of Dietary Behaviors, Food Consumption Frequency and Blood Clinical Indices by Residence Types of Female College Students in Seoul: Ru Zi Lee, Jung Hee Kim; Korean J Community Nutr 2019;24(3):183-196. Published online June 30, 2019; DOI: https://doi.org/10.5720/kjcn.2019.24.3.183

OBJECTIVES
College is an important time for students to establish their identity as an independent subjects and develop a foundation to maintain a healthy adulthood. However, after female students become college students, their eating habits are likely to become more irregular and they may experience various health problems because of excessive weight control. Therefore, this study was conducted to investigate the dietary behaviors and blood clinical indices of female college students by residence types.
METHODS
A total of 374 subjects were classified as home group, self-boarding group or boarding group according to residence type. Dietary habits, frequency of food intake, and eating attitudes were examined through questionnaires and anthropometric measurements and blood clinical indices were analyzed.
RESULTS
The meal most frequently skipped by female college students was breakfast, and the frequency of skipping breakfast was significantly lower in the home group than other groups. Most college students recognized that their eating habits had worsened since becoming college students, with the self-boarding group in particular feeling that their eating habits changed negatively. The consumption frequencies of protein foods, fruits, dairy products, seaweed, and fatty meats were significantly lower in the self-boarding group than other groups. The home group ate food cut into smaller pieces, while the self-boarding group tried new and rich foods. Residence types did not affect blood clinical indices.
CONCLUSIONS
The self-boarding group had inadequate dietary habits compared to the home group. Although residence type did not affect the blood clinical indices, the students still had poor dietary habits. Therefore, proper nutrition education is needed to improve the nutritional status of college students, especially those that self-board.

Comparison of Dietary Behaviors and Blood Clinical Indices in Underweight, Normal Weight, Normal Weight Obese and Obese Female College Students: Su Bin Lee, Jung Hee Kim; Korean J Community Nutr 2018;23(5):431-443. Published online October 31, 2018; DOI: https://doi.org/10.5720/kjcn.2018.23.5.431

OBJECTIVES
Normal weight obesity (NWO) is defined as excessive body fat in the context of a normal body mass index (BMI). This condition carries a greater risk of developing noncommunicable chronic disease and has been associated with early inflammation. This study was conducted to compare the anthropometric measurements, eating behaviors, and blood clinical indices among four groups: underweight, normal, normal weight obesity and obesity.
METHODS
The subjects included 215 female college students. A questionnaire was administered regarding general characteristics, dietary behaviors, food consumption frequency. Anthropometric measurements and blood clinical indices were also investigated.
RESULTS
The average BMI, body fat percentage, waist circumference, fat-free mass, and muscle mass were highest in the obesity group (p < 0.05). Most subjects had tried to lose weight and perceived that their health was worse than before they became college students. The ratio of students in the NWO group who thought their health was very poor was significantly higher than in the other three groups (p < 0.05). The obesity and NWO groups seemed to eat more and their eating speed was significantly faster than the other groups (pv0.001). The consumption frequency of caffeinated beverages was significantly higher in the NWO group than in the other three groups (p < 0.01). WBC was significantly higher in the obesity group (p < 0.05). Serum levels of TG and total cholesterol were also significantly higher in the obesity group (p < 0.05). Serum GPT was significantly higher in the obesity group (p < 0.05) while BUN level was highest in the NWO group (p < 0.05).
CONCLUSIONS
The obesity group showed the most health problems while the NWO group seemed relatively healthy. However, NWO can lead to problems such as metabolic syndrome and cardiovascular disease in later life if poor dietary habits are maintained. Therefore, education in appropriate eating habits is needed for these subjects.

Food Intake Patterns and Blood Clinical Indices in Female College Students by HDL-cholesterol Levels: Ha Na Jung, Jung Hee Kim; Korean J Community Nutr 2008;13(1):100-110. Published online February 29, 2008

Abstract PDF: Recently, a lot of epidemiological studies revealed that low HDL-cholesterol level was a better predictor of risk for coronary heart disease than total cholesterol. This study investigated the anthropometric parameters, clinical blood indices, and dietary factors influencing serum HDL-cholesterol level by using a cross-sectional study for Korean female college students. The subjects were 94 female college students. They were divided into three groups according to their serum HDL-cholesterol levels, low HDL-cholesterol (< 50 mg/dL, n = 20), medium HDL-cholesterol (50< or =, < 60 mg/dL, n = 39) high serum HDL-cholesterol groups (60< or = mg/dL, n = 35). This study examined their demographic data and dietary intake throughout a questionnaire. Clinical blood indices were measured using an automatic blood chemistry analyzer (Selectra E), after 12 hours of fasting. BMI, body weight, fat mass, and waist circumferences were significantly increased according to low serum HDL-cholesterol levels. Serum lipid analysis showed a significantly higher level of TG, LDL-/HDL-Ratio, atherogenic index in the low HDL-cholesterol group. Serum levels of GPT, uric acid and alkaline phosphatase in the low HDL-cholesterol group were significantly higher than in the other group. The average consumption of energy was 1627 kcal and 77.76% of estimated energy requirement (EER). The mean ratio of calories from carbohydrate : protein : fat was 57 : 15 : 28. The low HDL-cholesterol group was significantly higher than the other groups in eggs, fat and oils consumption. Interestingly, milk and diary products consumption of low HDL-cholesterol group was half (p < 0.05) of those of the other groups. In conclusion, serum HDL-cholesterol levels appeared to be decreased by increasing BMI, fat mass, waist circumference, and serum TG level. In addition, some dietary factors seemed to be related to serum HDL-cholesterol levels. However, further research is needed to elucidate the exact relationship between serum HDL-cholesterol level and dietary factors.
